Thank you for your thoughtful reply! I appreciate the encouragement and also your spot on suggestions, they’re all lovely. I also saw the [name_m]Aven[/name_m] post and thought how sweet, it’s a beautiful name. [name_m]Ever[/name_m], [name_m]Atlas[/name_m], [name_m]Emrys[/name_m] and [name_m]Hollis[/name_m] are all up there. [name_m]Cosmo[/name_m] I love but is my sisters dogs name.
Funny you should suggest experimenting with [name_m]Blue[/name_m], [name_m]Ocean[/name_m] has been saying the baby’s name is [name_m]Blue[/name_m] for some weeks now! I think no matter what, [name_m]Blue[/name_m] will be a nickname 
You’re so right, everyone is getting more and more used to unusual names and by the time he’s grown his will most likely not seem out of place.
